The idea about supporting weight of concert sets is more likely due to the roof shape, not foundation. The whole point of the normal dome shaped roof distributes the load, where a saddle roof would concentrate it, and limit its relative ability to support hanging loads.
Frankly I could see how the existing roof is heavier than a more conventional new roof based on its design. (And reinforcement requirement to bear its own load)
Sorry. Doesn’t pass the sniff test at the depth and certainty of your declaration.
I get that there would be potential compromises on design and functionality and building my from scratch gives you a blank canvas. That is fine.
I don’t know. I saw a game in Edmonton. It was a newer building with some nice features, and some flaws. Good music and Edmonton lost 4-0 so it could have been worse.
Fact is the economics of a new arena stink. It is a vanity project. Maybe the owners have decided they need it but that’s what it is.

The current Saddledome roof is literally supported on cables. A replacement roof would be supported on huge steel trusses - much much heavier.
Also, the way the roof is supported on cables exerts on force of the Saddledome walls - essentially pulling them towards the centre. That’s why the Saddledome walls lean outward - in part to counteract this force from the roof pulling them inward. This force is quite significant in a design like the Saddledome.
Now, if you replace the roof with a more standard arched roof, that inward force on the walls is gone, and most likely, the roof actually would exert force pushing the walls outward, instead of inward (All Trusses do this, and it needs to be taken into account by the structural engineering). There is a near zero chance that the walls could support a different roof for that reason alone.
In short, it doesn’t work.
